Left-edge: Aligns selected objects vertically along their left edges.
Vertical-center: Aligns selected objects vertically on their horizontal centers.

If you select objects that are arranged horizontally and choose a vertical alignment (or vice versa), the objects will end up on top of one another. You can unstack the objects by choosing Distribute from the pop-up menu immediately after the align function (the objects will still be selected). See "To Distribute Control Objects Evenly" for instructions.
